JAMES A. SEYMOUR, AUBURN, NEWV YORK.

GOVERNOR FOR STEAM-ENGINES.

SPECIFICATION forming part of Letters Patent No. 417,515, dated December 17, 1889.

Application filed February 14. 1889. Serial No. 299,856. (No model.)

A is a'shaft; B B, a wheel thereon, which furnishes a frame for the governor, and by whose revolution the governor is actuated.

w w are two weights, pivoted at p to the wheel B B, either together, as is shown in Fig. 2, if it is desired to use a double spring,

or at opposite sides of the wheel B B if it is" desired to use two single springs, as shown in Fig. 1. A sprlng s, Fig. 2, or two springs s s, Fig. 1, secured to the wheel 13 B, serve to press the Weights w w toward the center and to counteract'their centrifugal impulse from the revolution of the wheel B B. The

spring or springs aforesaid are supplied at their free extremities with cups 0 c, and the contrary direction, the centrifugal force of the weights to the spring or springs.

The movement of the weights w w to or from the center serves to throw an eccentric of usual construction across theshaft A, said eccentric being connected to said weights in any of the usual methods common to this class of governors, and thereby the throw of a valve operated from said eccentric is changed and the engine governed accordingly.

The new feature of this invention consists in the use of the pins 61 d, instead of the usual connecting mechanism between the spring or springs and the weights, whereby simplicity of construction and great sensitivencss of operation are attained.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

'The combination of the weights to w, provided with recesses c c, with the spring or springs provided with the cups 0 0 upon the free extremities thereof,'and the straight double-pointed pins 61 d, having their extremities supported within said recesses and cups, respectively.
